Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered (rectangular) cross section (now commonly used with rounded copper bars to avoid tip discharge) Circuits from the transmission current and the role of connecting electrical equipment. Copper in the electrical equipment, especially complete sets of power distribution equipment has been widely used; generally in the distribution cabinet U, V, W busbars and PE busbars are used copper bar; copper standard in use Colored letters or painted with color paint, U phase copper coated with "yellow" color, V phase copper coated with "green" color, W phase copper coated with "red" color, PE busbar copper coating There are "yellow and green and white" color.

Copper bar is a high-current conductive product, suitable for high and low voltage electrical appliances, switch contacts, power distribution equipment, busbar and other electrical engineering, but also widely used in metal smelting, electroplating, chemical caustic soda and other large current electrolytic smelting works. Electrical copper has low resistivity, bending can be large and so on.

Copper busbars, also known as copper busbars, copper busbars or copper busbars, ground copper busbars, are long conductors made of copper with a rectangular or chamfered (rectangular) cross-section and are made of aluminum material called aluminum Row, in the circuit from the transmission current and the role of connecting electrical equipment. The quality requirements of copper bus is GB / T 5585.1-2005 standard.
